AbstractObservations of the Jovian upper atmosphere at high latitudes in the UV, IR and mm/sub-mm all indicate that the chemical distributions and thermal structure are broadly influenced by auroral particle precipitations. Mid-IR and UV observations have shown that several light hydrocarbons (up to 6 carbon atoms) have altered abundances near Jupiter’s main auroral ovals.

Astrophysical ices are observed in various environments, in the icy grains of the interstellar medium (Wooden et al. 2004), in Solar system bodies such as the icy moons of Jupiter or Saturn systems or in comets. In such environments, ices present various compositions (Mumma & Charnley 2011) and are submitted to different physicochemical alterations (Ciaravella et al. 2020), heating histories (Mousis et al. 2016), as well as different irradiation types (Islam et al. 2014).
